The "bump" in question is actually a vent for the engine oil tank which sits directly below it. The bump is oval shaped with the back end cut off. (Think of a scoop turned around backwards.) to create a negitive air flow, exhausting hot vapors from the cowling. As an aside, the oil tank is rubberized much like a self sealing fuel cell and is accessed through a small door on the right side of the fairing for servicing.
